I think for communicating the various steps, participants would need to be 'friends' or have a quiet chat room to discuss the ongoing event details (eg. the Tournaments chat room). And, for pairing purposes, you just about need to be 'friends' so you can directly 'challenge' each other.

While Club Cafe's fine for reaching a wide audience to gather together interested entrants, it's just too busy at times to be used to tournament pairings etc.
